Focus Bracketing with Olympus OM-1

Introduction

• Experimenting with focus bracketing mode on Olympus OM-1 camera.
• Previous experience with in-body stacking mode has limitations.

Focus Stacking vs. Focus Bracketing

Limitations of Focus Stacking

• Can only take up to 15 images at a time.
• Requires a pause after stacking to process images.

Advantages of Focus Bracketing

• Can take up to 100+ photos at a time.
• Enables manual stacking on the computer after shooting.
• Allows for better control over focus points and avoids issues with moving subjects.
• First photo is always at the current focus point, offering more predictability.

Settings Used

• Maximum of 30 photos per stack set in bracketing mode.
• Focus differential set to 4, optimal for Olympus 60mm lens and Raynox 250.
• Ability to abort stacking by pressing shutter again if needed.

Photography Tips

• When working with insects, rest the subject on the lens for stability.
• Hold the leaf or surface where the insect is located for better support.
• Adjust flash strength as needed; reduced from 1/16 to 1/32 for longer stacks.

Observations During Shooting

• Encountered fast-moving subjects; focused on stable insects.
• Importance of stability emphasized for successful stacking.

Post-Processing Experience

• Some stacks resulted in artifacts; variability in quality of results.
• Example of a successful stack: photo of a yellow ladybug.
• Quick stacking in Photoshop used; layers aligned and blended.

Lessons Learned

• Fast memory card recommended to handle high volume of photos (260 MB/s).
• Came home with 1600 photos; many were not useful due to moving subjects.
• Suggested to use single picture mode as default.
• Activate bracketing mode only when a good subject is identified.

Conclusion

• Focus bracketing mode is preferred over stacking mode for macro photography.
• Overall positive experience with less waiting time between shots.
• Emphasizes being mindful when capturing photos to avoid unnecessary shots.
• Encouragement to subscribe for more macro photography content.
